Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following critical parameters:

• Connector type (Receptacle)
• Number of positions (6)
• Pitch and row spacing (0.079" / 2.00mm)
• Mounting type (Surface Mount)
• Contact type (Female Socket)
• Fastening mechanism (Push-Pull)
• Termination method (Solder)
• Contact finish (Gold)

The three identified substitute parts meet these core mechanical and electrical compatibility criteria. Variations in operating temperature range, current rating, voltage rating, insulation material, and contact finish thickness are noted but do not preclude functional substitution where application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

All four connectors are active products with ROHS3 compliance and MSL Level 1 rating, meeting regulatory and environmental requirements for industrial and telecommunications applications.

Harwin M22-6340342 provides increased current capacity (2A) and voltage rating (500VAC) with UL94 V-0 flammability certification. Operating temperature range is reduced to -40°C ~ 105°C. This part is suitable for applications requiring higher electrical performance within the specified temperature window.

Samtec MMS-103-02-F-DV maintains the full operating temperature range (-55°C ~ 125°C) of the original part and offers the highest current rating (3.9A per contact) with Liquid Crystal Polymer insulation. This part provides direct thermal compatibility with the Molex 0791098652.

Sullins NPPN032FFKP-RC is classified as a header connector rather than a receptacle, with operating temperature limited to -40°C ~ 105°C and 2A current rating. This part includes board guide features and UL94 V-0 flammability certification. Selection requires confirmation of connector style compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M22-6340342 be used as a direct replacement for the Molex 0791098652?

A: The Harwin part shares identical pitch, row spacing, number of positions, and mounting type. However, the operating temperature range is reduced from -55°C ~ 125°C to -40°C ~ 105°C. Direct substitution is valid only if the application operates within the -40°C ~ 105°C window.

Q: What is the difference between the Samtec MMS-103-02-F-DV and the original Molex part?

A: Both parts maintain identical operating temperature range (-55°C ~ 125°C) and pitch specifications. The Samtec part offers higher current capacity (3.9A per contact versus 1A) and uses Liquid Crystal Polymer insulation instead of glass-filled thermoplastic. Mechanical and electrical compatibility is maintained.

Q: Why is the Sullins NPPN032FFKP-RC listed as a header rather than a receptacle?

A: The Sullins part is classified as a header connector based on manufacturer designation. It maintains the same 6-position, 0.079" pitch, surface mount configuration, and push-pull fastening. Substitution requires confirmation that the application design accommodates header-style connector geometry.

Q: Are all substitute parts compatible with the same mating connectors?

A: All parts share the same pitch (0.079" / 2.00mm), row spacing, and number of positions. Mating compatibility depends on the specific connector design of the mating part. Physical dimensions and contact geometry should be verified against the mating connector specification.

Q: What is the significance of contact finish thickness variations?

A: Contact finish thickness affects durability and wear resistance. The Molex part specifies 30.0µin (0.76µm) mating contact finish, while Harwin and Sullins specify flash thickness. Samtec specifies 3.00µin (0.076µm). Flash finishes provide adequate protection for standard applications; thicker finishes offer extended contact life in high-cycle mating environments.

Q: Can these parts be used interchangeably in high-temperature applications?

A: The Molex 0791098652 and Samtec MMS-103-02-F-DV both support -55°C ~ 125°C operation. The Harwin M22-6340342 and Sullins NPPN032FFKP-RC are limited to -40°C ~ 105°C. Selection for high-temperature applications must be based on the specific upper temperature requirement.
